Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.
Answer:
C.
It can be read as...
".75 was charged for skates, and 1.25 was charged per hour for a total of 4.50."
No other answer choice has this. A does not have the variable h, B includes .75 which is NOT charged per hour, as well as D.
I hope this helps you!
I dont know if im correct but i think its C
first is 134.24
second is 452.16
third is 904.32
fourth is 2612.48 ft3
fifth is 42.39
plz mark brainly have a great rest of ur day :D
Answer:
i) 9
ii) 19 pens, 7 pencils, 3 erasers
Step-by-step explanation:
i) 171 = 3² x 19
63 = 3² x 7
27 = 3³
Highest Common Factor/HCF (171, 63, 27) = 3² = 9
Largest no. of bags = 9
ii) In each bag,
No. of pens = 171 / 9 = 19
No. of pencils = 63 / 9 = 7
No. of erasers = 27 / 9 = 3
